After KB4284835 was installed I discovered any Macrium backups were crashed (ditto Windows image backup, now dated / defunct) and the only quick effective solution was to disable / hide it via wushowhide. diagcab. (This was also reported on Microsoft’s community posts to which I offered my fix).

I also unticked the config box to de-enable Windows updates, hence the above KB..835 cannot be forced in again. This was the only issue I had noted but only having it installed for a week. [I usually backup weekly (Win10 Home, but have two clones of this that I like to keep at less frequent backups].
